Hytale Server Requirements: RAM, CPU and Java
A Hytale dedicated server is a real headless Java application, so its requirements sit closer to a Minecraft server than a lightweight lobby. The official minimum is Java 25 and at least 4 GB of RAM, but the figure that actually decides your plan is view radius multiplied by how many players explore separate areas at once.
Match a 4, 6 or 8 GB managed Hytale plan to your group
The official minimum
- Java 25, with Adoptium Temurin recommended by Hypixel Studios;
- at least 4 GB RAM, with more for wider views and players who explore independently;
- an x64 or arm64 host;
- one reachable UDP port, 5520 by default;
- an authenticated Hytale game session before anyone can join.
Four gigabytes is a floor, not a target. A server that idles comfortably at 4 GB can still run out of headroom once several players load separate regions.
What actually drives memory use
Two things move RAM more than raw player count:
- MaxViewRadius. Each chunk column the server keeps loaded costs memory and CPU. The official guidance keeps this near 12 chunks unless monitoring shows room for more. Raising it widens every player's loaded area at once.
- How spread out players are. Ten players standing together load one shared area. Ten players heading in ten directions load ten areas. The second case is what exhausts a small plan.
Mods add to this. Server-side content in Server/mods can raise both the memory baseline and per-tick CPU, so leave headroom when you run them.
Sizing against GHosting plans
GHosting offers Hytale on 4, 6 and 8 GB plans. As a starting point rather than a hard rule:
- 4 GB: the official minimum. A small group at the default view radius with few or no mods.
- 6 GB: a more active group, a somewhat wider view radius, or a modest mod set, with room to breathe.
- 8 GB: a larger community, players exploring separate regions, a higher view radius, or heavier mods.
Pick by how your players actually behave, then watch real usage and move up only when headroom gets tight. It is easier to raise a plan than to recover a server that is thrashing.
CPU, disk and network
World generation and simulation lean on single-thread performance, so a fast core matters as much as core count for a small server. Keep enough disk for the world under Server/universe plus backups, and remember Hytale connects over QUIC on UDP, so the network path needs that one UDP port open from end to end.
Managed alternative
A GHosting Hytale server ships the official Java 25 build on a plan you can resize, exposes the UDP port, and keeps worlds and backups, so you can start at 4 GB and move up without rebuilding anything. The upstream requirements are in the official Hytale Server Manual.
